If someone manages to run this exploit thru geohot's they might actually execute it and get CORE Files (COREOS) DECRYPTED and a DES KEY (Which sounds to me as the masterkey) but i'm 85% sure i'm wrong about the DES KEY.

First is an FTPd exploit. The PS3 does not run a FTP server.
Second is a portmapper exploit. The PS3 has no NFS / ... server.
The third requires a shell on AIX with a standard libc. I have seen no evidence of either being available.

(The mention of DES keys here is related to logon credentials, which again do not exist on the PS3)
